Tuzistra XR is the only FDA-approved 12-hour codeine-based antitussive. Tuzistra XR is a prescription antitussive consisting of codeine polistirex and chlorpheniramine polistirex in an extended-release oral suspension.

Along with Tuzistra XR, the Company has licensed a complementary antitussive product pending FDA approval. Tuzistra XR and the complementary antitussive, upon FDA approval, will both be marketed in the United States by Aytu’s direct sales force. Tuzistra XR is expected to generate revenue this year after launching promptly this cough and cold season. Tuzistra XR generated more than 40,000 prescriptions in 2017.

Tuzistra XR is a patented combination of codeine, an opiate agonist antitussive, and chlorpheniramine, a histamine-1 receptor antagonist, indicated for relief of cough and symptoms associated with upper respiratory allergies or a common cold in adults aged 18 years and older. Tuzistra XR is protected by two Orange Book-listed patents extending to 2031 and multiple pending patents.

According to MediMedia, the US cough cold prescription market is worth in excess of $3 billion at current brand pricing, with 30-35 million annual prescriptions. This market is dominated by short-acting treatments, which require dosing 4-6 times a day. Tuzistra XR was developed using Tris Pharma's liquid sustained release technology, LiquiXR®, which allows for extended drug delivery throughout a 12-hour dosing period.

As part of this transaction, the Company also plans to enter into a strategic financing with Armistice Capital, LLC (“Armistice”), an institutional healthcare investor with over $800M in assets under management. Under the terms of this financing, Armistice is expected to provide the company with up to $5 million in the form of a three-year note, secured by the Tuzistra revenue streams. This funding will further support the Company’s growth and enable a rapid launch and integration of the Tuzistra portfolio in Aytu’s current operations. Details of the financing will be provided upon its closing, which is expected to occur in seven business days.

Josh Disbrow, Chief Executive Officer of Aytu BioScience explained, “We are thrilled to be partnering with Tris Pharma in acquiring this license to Tuzistra XR and the complementary antitussive therapeutic pending approval. We believe these products align well with our primary care portfolio, and Tuzistra XR provides another attractive, revenue-generating therapeutic asset with clear clinical differentiation and patient benefits. We’re equally excited about the prospect of adding a complementary antitussive to the portfolio as that product gains approval. We thank the Tris Pharma team for entrusting Aytu to build these products into strong brands and look forward to a successful long-term relationship with Tris.”

Tris Pharma’s Founder and Chief Executive Officer, Ketan Mehta said, “The combination of all day, all night, cough/cold relief in a liquid form makes a great deal of sense. We are excited to continue to leverage our technology platform, LiquiXR, to improve patient care. Further, we are delighted to have Aytu BioScience as our partner.”
